hexamethyleneamine是什么意思，hexamethyleneamine翻译

Hexamethyleneamine, also known as hexamethylene diamine, is an organic compound with the molecular formula C?H??N?. It is a colorless liquid with a faint amine odor. This compound is widely used in the chemical industry as a key intermediate in the production of polyurethane, adhesives, and coatings.

Hexamethyleneamine is synthesized by the reaction of formaldehyde with ammonia in the presence of a base. The reaction is typically carried out at low temperatures and high pressures. The synthesis of hexamethyleneamine involves the formation of a Schiff base intermediate, which is then dehydrated to yield the final product. This process requires careful control of reaction conditions to ensure high yield and product purity.

In the production of polyurethane, hexamethyleneamine serves as a chain extender. It reacts with polyisocyanates to form urethane linkages, which are responsible for the polymer's elastic properties. Hexamethyleneamine is also used in the production of polyurea coatings, which are known for their excellent durability and resistance to chemicals.

In addition to its use in polyurethane production, hexamethyleneamine finds applications in other industries. It is used as a raw material in the synthesis of N,N'
